Make It Your Way

I love to shake things up when I make this Crumbl Monster Cookie Recipe—sometimes I swap peanut butter chips for butterscotch or add a handful of chopped nuts for extra crunch. The beauty is, these cookies are so forgiving and versatile that your creativity is the only limit.

  • Variation: Adding chopped pecans or walnuts gives a lovely texture contrast—I’ve done this when baking for family gatherings, and they disappear fast!
  • Dietary Modifications: You can use dairy-free butter and egg substitutes to make them vegan-friendly; just keep the baking soda and flour ratios the same.
  • Seasonal Changes: Try swapping M&M’s for seasonal candies like peppermint chips in winter for a festive twist.

Step-by-Step: How I Make Crumbl Monster Cookie Recipe

Step 1: Cream It Right

Start by preheating your oven to 325°F and lining a baking sheet with parchment paper—this is key to prevent sticking and promote even baking. In a large bowl or stand mixer, beat the softened butter with brown and granulated sugars until it’s light, fluffy, and creamy. This step usually takes about 3-5 minutes. Trust me, taking time here ensures a tender base for your cookies and helps dissolve the sugars for the best texture.

Step 2: Mix in the Flavor Builders

Next, crack in the egg and add your vanilla extract. Mix just until combined—overmixing here can toughen your cookies later. I usually pause and scrape the sides of the bowl to make sure everything melds nicely before moving on.

Step 3: Add Dry Ingredients and Mix-Ins

Sift in the flour, baking soda, and salt—sifting is a small step that helps avoid lumps and evenly distributes baking soda for a consistent rise. Mix on low speed just until you no longer see flour. Now, here’s the most fun part: gently fold in your M&M’s, peanut butter chips, and chocolate chips. Be gentle so the candies keep their shape and don’t get crushed or melt prematurely.

Step 4: Scoop and Bake

Using a large cookie scoop, portion out 8 even dough balls onto your prepared sheet. Press each slightly to about an inch thick—that helps them bake evenly without spreading too thin. Pop them in the oven for 12-13 minutes until the edges are just set but the centers still look a little soft. They’ll firm up as they cool.

Step 5: Add a Final Candy Touch

Right out of the oven, press a few extra chocolate chips, peanut butter chips, and M&Ms on top of each cookie. This gives them that irresistible, colorful Crumbl look we all love. Let the cookies rest on the baking sheet for about 20 minutes to fully cool and set before you dig in.

Tips from My Kitchen

  • Soft Butter Is Key: Using cold butter straight from the fridge didn’t work well for me—softening it properly helps with better creaming and loosens the dough.
  • Don’t Overbake: Cookies look a bit undercooked when you pull them out, but that’s perfect—they firm up while cooling and stay chewy.
  • Press Extra Candies After Baking: This adds texture and makes the cookies look extra inviting, just like Crumbl’s signature style.
  • Use a Large Scoop for Even Cookies: I switched to a 1/4 cup cookie scoop, and it really helps the cookies bake uniformly every time.

How to Serve Crumbl Monster Cookie Recipe

Garnishes

I like to sprinkle a pinch of flaky sea salt on these cookies just before serving. It might sound odd, but the little salty crunch offsets the sweetness so beautifully. Sometimes I also add a drizzle of melted peanut butter over the top for an extra creamy finish when serving at parties.

Side Dishes

Pair these monster cookies with a tall glass of cold milk—classic and always satisfying. For a grown-up twist, I love serving them alongside coffee or even a scoop of vanilla ice cream to turn dessert time into an indulgent celebration.

Creative Ways to Present

If you’re hosting a birthday or a fun get-together, arrange your Crumbl Monster Cookies on a colorful platter with fresh fruit or edible flowers around the edges. I even tried stacking a few with parchment paper in between for a cookie tower centerpiece that was a huge conversation starter!

Make Ahead and Storage

Storing Leftovers

After baking, these cookies keep best in an airtight container at room temperature for up to 4 days. I usually store mine like this when I want them ready for quick snacks, but be sure to keep them away from heat sources so they don’t get too soft or sticky.

Freezing

Freezing these monster cookies works like a charm for longer storage. I freeze them individually on a tray, then transfer to a freezer-safe container or bag. This way, I can grab just one or two at a time, and they stay fresh for up to 2 months without a hint of freezer burn.

Reheating

When I want that fresh-baked feel, I pop frozen or refrigerated cookies in the microwave for about 10-15 seconds. They come out soft and gooey again, just like right out of the oven. Just be careful not to overheat—they can get chewy or hard if left too long.

FAQs

  1. Can I use salted butter for this Crumbl Monster Cookie Recipe?

    Yes! Both salted and unsalted butter work well here. If you use salted butter, you might want to reduce the added salt to balance the flavors. I often use salted butter simply because that’s what’s in my fridge—makes it super easy.

  2. Why do we add the candy chips after baking instead of mixing all in the dough?

    Adding extra M&M’s and chips right after baking preserves their vibrant colors and prevents them from melting too much into the cookie. This way, your monster cookies keep that signature colorful, glossy look, and every bite has a fun texture contrast.

  3. Can I make smaller cookies with this recipe?

    You absolutely can! Just reduce the baking time to about 9-10 minutes to avoid overbaking. Smaller cookies are great for parties or if you want more cookies to share—but they won’t be as chewy and oversized as the original monster style.

  4. How do I keep my cookies soft and chewy?

    The key is not to overbake them and to use a good balance of brown sugar and butter. Also, letting the cookies rest on the baking sheet after baking allows residual heat to finish the job gently, locking in that soft, chewy texture.

Final Thoughts

This Crumbl Monster Cookie Recipe is honestly one of my all-time favorites to bake when I crave a cookie that feels like a celebration in every bite. It’s fun, forgiving, and packed with flavors that everyone loves—whether you’re an experienced baker or just starting out. I hope you have as much joy making and eating these as I do. Trust me, once you try it, you’ll want to keep this recipe close for every cookie craving that comes your way!
